python模擬http請求

下文主要講述如何利用python自帶的庫模擬http請求，爲以

#!coding:utf-8 相信這句你們都懂的，不解釋

#導入須要的python模塊httplib，用來模擬提交http請求，詳細的用法可見python幫助手冊

import httplib

#導入須要的python模塊urllib，用來對數據進行編碼
import urllib
#定義請求頭

reqheaders={'Content-type':'application/x-www-form-urlencoded',
'Accept':'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
'Host':'www.renren.com',
'Origin':'http://zhichang.renren.com',
'Referer':'http://zhichang.renren.com',
'User-Agent':'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.89 Safari/537.1',}

#定義post的參數

reqdata={'email':'xxxx@xxx.com',
'password':'xxxx',
'autoLogin':'on',
'origURL':'http://zhichang.renren.com/?login_state=rr',
'domain':'renren.com'
}

#對請求參數進行編碼

data=urllib.urlencode(reqdata)

#利用httplib庫模擬接口請求

#先鏈接到人人

conn=httplib.HTTPConnection('renren.com')

#提交登陸的post請求
conn.request('POST', '/PLogin.do', data, reqheaders)

#獲取服務器的返回
res=conn.getresponse()

#打印服務器返回的狀態
print(res.status)

#以dictionary形式答應服務器返回的 response header

print(res.msg)
#打印服務器返回請求頭中設置的cookie
print(res.getheader('Set-Cookie'))

#如下爲運行程序後的結果
登陸成功後重定向了

#如下就是cookie了，之後發請求，就能夠帶上這個cookie

後利用python作API測試作準備。

只講述模擬http的過程，具體到本身用的時候，要以本身的應用爲準作出適當的調整。
